Answer:
She warns that men who did not give their wives authority would be unhappy.
Explanation:
Geoffrey Chaucer's "The Wife Of Bath's Tale" revolves around the issue of the obedience of men to their wives and the need to give authority over all things to women. Only when (and if) women are given the power to chose and make decisions can there be peace, and everyone can live happily. That was what the Wife of Bath was implying through her story of the knight and the old woman.
By narrating the success story of how a knight was saved by an old woman, and how his obedience in obeying her led to his 'happily ever after', the Wife of Bath's tale is suggestive of the need for woman to have or rather, be given dominance over the men in general. After she successfully gets done with her storytelling, she ends with a warning "eek I pr ye Iesu shorte hir lyves
/ That wol nat be governed by hir wyves;
/ And olde and angry ni gardes of dispence,
/ God sende hem sone verray pestilence".
